How to eat roughage with a weak spleen and stomach?

For people with weak spleen and stomach functions, will eating more coarse grains aggravate their burden? Is it easier to digest refined rice and white flour? For the consumption of coarse grains and potatoes, people sometimes have a superficial understanding – not easy to digest, that is, it will increase the burden of gastrointestinal digestion, so the healthy people with normal gastrointestinal function is okay, if there are gastrointestinal diseases or weak spleen and stomach, is not it should not choose coarse grains or potatoes and go to choose easy to digest refined rice and white flour? In fact, not. The reasoning is as follows: first of all, for gastrointestinal dysfunction, more should eat coarse grains or potatoes, because these than refined rice and white flour nutrient-rich, rich in more vitamins and trace elements, is conducive to the health of the digestive mucous membrane barrier and promote the secretion of digestive juices, and through the stimulation of dietary fiber to speed up the gastrointestinal peristalsis. Secondly, we take for granted that the word “coarse” from the coarse grains is understood as “rough”, “hard” and not easy to digest…. …If the same cooking conditions as refined rice and white flour are a bit difficult to digest, why don’t we make coarse grains and potatoes soft enough before they are eaten? For example, the steamed grains or potatoes in a pressure cooker will melt in your mouth (think of the texture of canned congee… rough?), and this way, the grains will be more digestible. In this way, the digestive burden of miscellaneous grains is not higher than that of refined rice and white flour. To summarize, eating mixed grains is to more nutrients to promote gastrointestinal function as soon as possible rather than a palliative, mixed grains are also able to completely soft and easy to digest without increasing the burden on the gastrointestinal tract. However, not all grains or potatoes are suitable for weak spleen and stomach, such as sweet potatoes are not suitable, yam is suitable; glutinous rice is not suitable, millet is suitable; miscellaneous legumes are not suitable, brown rice pumpkin is suitable.
